Menstruation is what most people call having your period.. The menstrual cycle is the time from the first day of one period to the first day of the next. A normal menstrual cycle can be as short as 21 days or longer than 35 days. For most women, it lasts 25 - 30 days.But it's common for your cycle to vary from month to month.Here are the basics: 1  You have two ovaries. Usually the egg and lining of tissue and blood comes out of your vagina at the end of your cycle. 2  This is called menstrual flow, or your period. 3  If sperm joins with an egg, it's called fertilization. 4  Pregnancy begins if a fertilized egg attaches itself to the thick lining of the uterus.
